Day 2 of DEF 2026 is an invite only gathering at DEF’s River House on the Potomac 45 minutes from DC and Alexandria.

Directly across the water from the famous Mt. Vernon estate in Bryans Road Md, the house sits nestled under the pines on a six acre waterfront estate. 

Spend the day with a smaller curated delegation of subject matter experts, practitioners, strategists and capital allocators for laid back conversation and time to truly connect. 

We will feast over an open fire Argentinian BBQ and hear salon style quick hit briefs but most importantly, we will celebrate, share and leverage DEF’s greatest asset - the community.

The attendee list will be curated to include those leading efforts in economic defense, critical mineral and supply chain efforts, and over the horizon national security investment and statecraft activity.
